The O-ring seals in the AC couplings can develop leaks. The condenser can also crack and leak, which is sometimes misdiagnosed as a leaking coupling.  The condenser cracks out of sight, under the radiator support, so it looks like the coupler is leaking. Leak testing with fluorescent dye will help locate the exact source of the leak.
